Intraluminal bypass device for arterial surgery.
Over 50,000 artificial grafts are implanted every year in the United States. Present surgical procedures require either bypass or clamping off of the vessel to be replaced. Complications of these techniques include aneurysms and left ventricular overload. In addition, for aortic procedures paraplegia or even death can occur. A simple surgical procedure that does not require cardiopulmonary bypass, external shunts, or cross-clamping was developed and tested in dogs. An intraluminal bypass device was developed to allow blood to flow through the aorta to the lower limbs during the procedure. Blood flow stoppage was minimized, which should lead to a reduction of morbidity and mortality.
